The wireless motion sensor uses an infrared sensor to accurately detect movements made by people/animals within 16.4 ft (5 m) range. User customization allows you to set notifications and alerts from the system to know immediately if there is motion in a given area.

In this issue

The new Monnit Battery Health Sensors are an analog voltage meters designed to measure battery voltage at specified intervals and wirelessly send the voltage readings to iMonnit, the online sensor monitoring system.

Features of the new wireless battery health sensor:
• Interfaces with batteries up to 48 VDC
• 0.025 VDC Voltage Resolution
• Operating temperature range of -20°C to 60°C
(10°C to 50°C recommended)
• At 1 hour heartbeat sensor will last over 1 year

Let's take a look in our crystal ball to see what the future holds at Monnit?

Monnit's development team is hard at work developing a new Wireless Inventory Management Sensor. The Inventory Management sensor uses a soft pot potentiometer to detect when pressure is applied to the top of the sensor ribbon. The sensor can detect and send an alert when inventories are getting low. This new addition to the Monnit product lineup should be available in the near future. If you would like to learn more about this product or be notified when it becomes available, please email us at sales@monnit.com.

There are numerous things you want to know about your boat when you are not there. Boat bilge pump failure can be catastrophic when it comes to your boat or watercraft staying afloat. Maybe you want to go out on the boat this weekend, do you know if the battery is still holding a charge? Monnit wireless sensors can let you know when an issue arise.

You want to know immediately so you can take care of problems before damage occurs or your boat submerges. With Monnit wireless water sensors you can know if the water in the bilge reaches a certain level and pump has not turned on indicating a pump issue. Wireless battery health sensors can let you know the amount of charge left on the boat battery, so you never have to worry about dead batteries.

The Monnit Wireless Pressure Sensor is capable of measuring gas, liquid or vapor pressures from 0-160 PSI. This solution uses a combination pressure gauge / transducer interfaced to a Monnit wireless radio. It is suitable for any application capable of using a bourdon-tube based pressure gauge. The use of pressure snubbers, pulsation dampeners, and other appropriate devices can increase the range of applications available to pressure gauges. It is a prudent practice to use these items in any type of precision pressure instrument.

Do not tighten using the case

When installing and tightening the gauge, apply a wrench to the wrench flats located just above the threaded portion of the pressure fitting only. DO NOT tighten by using the gauge case housing, even by hand, as this may damage the unit or cause a calibration shift.

Suitable Sealing Method on Threads

For gauges with NPT type pressure fittings, apply Teflon tape or an equivalent appropriate sealant to the threads before installing to ensure a leak free connection. Even a very small leak may cause an inaccurate reading.

Vibration and Pulsation

The unit can withstand normal gauge vibration without damage or significant output effects. However, it is a good practice to mount the pressure gauge where vibration is minimized. In addition, it is a good practice to use an appropriate throttling device to decrease the effects of more severe pressure pulsation and/or vibration on pointer movement, including throttling screws, pulsation dampeners, elastomeric bladders and pressure snubbers.

Adjustment of Zero and Span

Adjustment of zero and span requires a specific factory procedure and pressure calibration standards. Do not attempt to do this without approval from the factory to avoid voiding the warranty.

Connecting Power to The Pressure Sensor

Take care when connecting the power source to the
Monnit wireless pressure sensor. The grey cable connects
the pressure gauge to the wireless radio. The two wires
coming out of the wireless tranceiver require 12-32 VDC
power which is passed to the pressure gauge / transducer
to enable operation.

Connect the positive side of the 12-32 VDC supply
power to the red lead wire and the negative side
to the black lead wire.

Note: The wireless radio requires 3 VDC and is powered by
either a coin cell battery, 2 AA batteries or a single 3V AA
battery, depending on sensor platform. Batteries are included
with the sensor when purchased.
